Abstract: A frame assembly for a scooter-type vehicle having at least one front wheel, at least one rear wheel and a vehicle body. The frame assembly includes a head tube, which supports a front wheel suspension assembly of the vehicle. An upper frame extends from the head tube to a rearward end of the vehicle body. A swingarm is pivotally supported by the upper frame and supports a rear wheel of the vehicle. The frame assembly may include a lower frame removeably coupled to the upper frame and defining a space therebetween. The lower frame preferably supports at least one component of the scooter-type vehicle in the space, such as a fuel tank, for example. In one arrangement, the upper frame includes a forward portion and a rearward portion. The rearward portion includes at least one elongated, channel-shaped frame member having a forward section and a rearward section.
